Abstract Background Inherited coagulopathies and previous thrombotic events are often considered relative contraindications to microvascular reconstruction. We hypothesize that with planning, head and neck microvascular reconstruction can be successfully performed in hypercoagulable individuals. Methods A retrospective review was conducted of subjects with coagulopathies or previous thrombotic events who underwent microvascular head and neck reconstruction. Outcomes studied were “flap-related complications” (arterial/venous compromise or flap loss) and “patient-related complications” (hematoma, deep venous thrombosis, pulmonary embolism, infection, stroke, or death). Results One hundred thirty-four microvascular flaps were performed in 117 subjects. Twenty-four subjects (20.5%) had a preoperative hypercoagulable condition and underwent 28 microvascular reconstructions. Twenty-three of 24 subjects had a previous thrombotic event, with five subjects identified with an inherited or acquired coagulopathy. All microvascular reconstructions were successful; however, complications occurred in 12 of 28 reconstructions (42.9%). Complications were “flap related” in four reconstructions (14.3%), “patient related” in nine reconstructions (32.1%), and both in one reconstruction (3.6%). Flap-related complications included small partial flap loss (n = 2), arterial compromise (n = 1), and venous compromise (n = 1), with all undergoing successful salvage. Patient-related complications included hematoma (n = 3), pulmonary embolism (n = 2), infection (n = 2), deep venous thrombosis (n = 1), and death (n = 1). Statistical analysis demonstrated that complications were more common in subjects with inferior vena cava filters (p = 0.06) and hematomas were associated with the use of therapeutic heparin infusion (p = 0.04). Conclusion Microvascular head and neck reconstruction can be successfully performed in hypercoagulable subjects. However, patient-related complications remain a concern in these subjects.

Abstract Background There is a steep learning curve to attain a consistently good result in microvascular surgery. The venous anastomosis is a critical step in free-tissue transfer. The margin of error is less and the outcome depends on the surgeon’s skill and technique. Mechanical anastomotic coupling device (MACD) has been proven to be an effective alternative to hand-sewn (HS) technique for venous anastomosis, as it requires lesser skill. However, its feasibility of application in emerging economy countries is yet to be established. Material and Method We retrospectively analyzed the data of patients who underwent free-tissue transfer for head and neck reconstruction between July 2015 and October 2020. Based on the technique used for the venous anastomosis, the patients were divided into an HS technique and MACD group. Patient characteristics and outcomes were measured. Result A total of 1694 venous anastomoses were performed during the study period. There were 966 patients in the HS technique group and 719 in the MACD group. There was no statistically significant difference between the two groups in terms of age, sex, prior radiotherapy, prior surgery, and comorbidities. Venous thrombosis was noted in 62 (6.4%) patients in the HS technique group and 7 (0.97%) in the MACD group (p = 0.000). The mean time taken for venous anastomosis in the HS group was 17 ± 4 minutes, and in the MACD group, it was 5 ± 2 minutes (p = 0.0001). Twenty-five (2.56%) patients in the HS group and 4 (0.55%) patients in MACD group had flap loss (p = 0.001). Conclusion MACD is an effective alternative for HS technique for venous anastomosis. There is a significant reduction in anastomosis time, flap loss, and return to operation theater due to venous thrombosis. MACD reduces the surgeon’s strain, especially in a high-volume center. Prospective randomized studies including economic analysis are required to prove the cost-effectiveness of coupler devices.

The placement of an inferior vena cava (IVC) filter is a therapeutic method for selected patients with deep venous thrombosis and pulmonary embolism. However, insertion and placement of the filter may be associated with certain complications. For instance, retroperitoneal hematoma resulting from perforation of the wall by the filter is such a very rare but serious complication. We report the case of a 64-year-old woman with perforation of the IVC wall and consecutive hematoma caused by the filter who was treated surgically.

The authors present a case of a 27-year-old multiparous woman, with multiple thrombophilia, whose pregnancy was complicated with deep venous thrombosis requiring placement of a vena cava filter. At 15th week of gestation, following an acute deep venous thrombosis of the right inferior limb, anticoagulant therapy with low-molecular-weight heparin (LMWH) was instituted without improvement in her clinical status. Subsequently, at 18 weeks of pregnancy, LMWH was switched to warfarin. At 30th week of gestation, the maintenance of high thrombotic risk was the premise for placement of an inferior vena cava filter for prophylaxis of pulmonary embolism during childbirth and postpartum. There were no complications and a vaginal delivery was accomplished at 37 weeks of gestation. Venal placement of inferior vena cava filters is an attractive option as prophylaxis for pulmonary embolism during pregnancy.

A clinical case of a 71-year old patient with stomach cancer and concomitant lower extremity deep venous thrombosis diagnosed before the surgical treatment is presented. The patient was administered anticoagulants, and despite the treatment, a diagnosis of deep venous thrombosis with high risk for thromboembolism was set up. Considering high risk for pulmonary embolism, an inferior vena cava filter was implanted in infrarenal part of inferior vena cava at the first stage. On the second day after the cancer surgery (subtotal stomach resection with lymphadenectomy), clot detachment and its dislocation from the left common femoral vein to the area where the cava filter was implanted with further fixation were diagnosed. Accurate diagnosis of lower extremity deep venous thrombosis with high risk for thromboembolism set up by ultrasonography and timely inferior vena cava filter implantation saved the patient with cancer from developing pulmonary embolism.

Acute deep venous thrombosis (DVT) of iliofemoral segment is one of the most dreaded presentations of venous thromboembolism, as it can not only compromise the function of the extremity but may also result in pulmonary embolism and even death. There are many causes for acute iliofemoral DVT, including underdiagnosed May-Thurner syndrome, hypercoagulable syndrome, and external compression on iliocaval segment. The available treatment depends on the acuity of the symptoms. Acute iliofemoral DVT can be treated with medical anticoagulation, pharmacomechanical therapy, including thrombolysis or surgical thrombectomy. Chronic iliofemoral occlusion may be treated with recanalization of the occluded segments with angioplasty stenting. This review contains 4 Figures, 4 Tables and 63 references Key Words: acute, angioplasty, deep venous thrombosis, iliofemoral, inferior vena cava, pharmacomechanical therapy, occlusion, stent

Abstract Background Although there are several potential recipient vessels in the neck, those in the temporal region are limited. In skull base reconstruction, there are difficulties associated with the anastomosing recipient vessels in the neck region since long nutrient vessels are needed in the flap. We evaluated the reliability of temporal vascular anastomosis by comparing surgical outcomes between reconstructive methods and examined which surgical procedures may achieve better results. Methods We examined the medical records of free tissue transfer cases between April 2007 and March 2018. Seventy-three surgeries were performed in the temporal region, including skull base reconstruction in 48, head and neck reconstruction (without skull base) in 16, and secondary surgery for head deformities in nine cases. In total, 445 neck surgeries were performed. Postoperative complications were retrospectively analyzed. Results The postoperative complication rates were 8.2 and 2.7% for all temporal and neck surgeries, respectively. There were no arterial complications in the temporal region and all of the six postoperative anastomotic complications were due to venous thrombosis. In contrast, there were 12 cases of vascular anastomotic complications, with six cases each of arterial and venous thrombosis in the neck. In the temporal region, the complication rate was 2.1% for skull base reconstruction, 11% for secondary revision, and 25% in head and neck reconstruction. The corresponding values for middle temporal vein (MTV) usage rates were 54, 22, and 25%. In skull base reconstruction, a coronal incision was made in all cases. A more frequent use of the MTV was associated with a reduced complication rate. Conclusion The low complication rate in the temporal region was attributed to the wide surgical field and low tension of anastomotic vessels. Multiple venous anastomoses, including those of the MTV, are recommended to prevent complications.

Background Due to limited evidence, it is unclear whether postoperative anticoagulation therapy may lead to higher success rates for microvascular free-flap surgery in the head and neck. This review evaluated whether postoperative anticoagulation therapy can lead to a better result in head and neck reconstruction. Methods PubMed, Embase, and the Cochrane Library were used to search for articles on the efficacy of postoperative antithrombotic therapy in free-flap transfer during head and neck reconstruction without language restrictions in February of 2017. A random-effects model was used to estimate the relative risk ratio (RR) with 95% confidence intervals (CIs). The measured outcomes were flap loss, thromboembolic events, and hematoma formation. Results A total of 2,048 free-flap surgery procedures in the head and neck were analyzed. There was no significant difference in the occurrence of flap loss and thromboembolic events in the anticoagulation group compared with the nonanticoagulation group (RR = 1.25, 95% CI = 0.85–1.81, p = 0.26; and RR = 1.05, 95% CI = 0.74–1.48, p = 0.79, respectively). The risk of hematoma was twice as high in the anticoagulation group than the nonanticoagulation group, which was statistically significant (RR = 2.02, 95% CI = 1.08–3.76, p = 0.03). Conclusion The findings from our meta-analysis indicate that postoperative anticoagulation therapy barely decreases the risks of flap loss and thromboembolic events in free-flap surgery in the head and neck. However, it may significantly increase the risk of hematoma formation. Considering the limitations of this meta-analysis, additional high-quality, multicenter, prospective, randomized controlled studies are needed to confirm these findings.
